Struct BoundingBox 

Source 
pub struct BoundingBox {
    pub min_lat: f64,
    pub min_lon: f64,
    pub max_lat: f64,
    pub max_lon: f64,
}
Expand description

A geographic bounding box for filtering tiles during preload.

Coordinates are in decimal degrees (WGS84).

Fields§

§min_lat: f64

Minimum latitude (southern boundary).

§min_lon: f64

Minimum longitude (western boundary).

§max_lat: f64

Maximum latitude (northern boundary).

§max_lon: f64

Maximum longitude (eastern boundary).

Implementations§

Source§

impl BoundingBox

Source

pub fn new(min_lat: f64, min_lon: f64, max_lat: f64, max_lon: f64) -> Self

Create a new bounding box.

§Arguments
  • min_lat - Southern boundary latitude
  • min_lon - Western boundary longitude
  • max_lat - Northern boundary latitude
  • max_lon - Eastern boundary longitude
Source

pub fn overlaps_tile(&self, tile_lat: i32, tile_lon: i32) -> bool

Check if this bounding box overlaps with a 1°×1° tile.

A tile at (tile_lat, tile_lon) covers the area [tile_lat, tile_lat+1) × [tile_lon, tile_lon+1).
